1969 Mark III Blower Motor Questions & Response

Bill,
I am currently working on the HVAC system on my 1969 Continental Mark III. I have read many of your posts and have learned and used a lot of your advice for my car. My car has the Automatic Climate Control and has a funny noise coming from the blower motor. From what I have learned so far it sounds very much like a bad bearing in the blower motor. My shop manual is not very clear on the removal of the blower motor.I have gotten as far as the recirculation diverter valve loose but the problem is I cannot seem to fully remove the valve assembly. It gets stuck about halfway of its travel coming out. I tried and tried to somehow find a way on how to properly remove the valve without damaging it but I had no luck. It would be great if you could lend me some of your advice and knowledge on how to remove it fully.
Thank you for your time and I would love to hear back from you!

Hi Jett –
The complete re-circ. assembly needs to be removed for access to the blower removal and not only the valve. This is probably what you are actually referring to. There is one vacuum and one electrical connector to unplug as well as the removal of six screws. The whole unit is then carefully pried from the original body caulking and rotated and pulled as necessary for removal. The removal of the glove box liner and the two screws for the fuse box and allowing it to pivot out of the way will allow you to see the operation much better. You may need to carefully observe and then loosen or remove some other component etc. that are blocking the path of removal. I have no other removal tips as I have never had any problems removing this assembly. The factory manual is short on the subject but there are some drawings to be found in the Heat/A/C section. Because of the removal labor, replacement of the motor with a new or one with good bearings is advised. We should have one available for you.
Sincerely,
Bill

Hi Bill,
Thank you very much for your reply. As it turns out I had to remove the ATC box and temporarily slightly bend the fuse box support to remove the recirc. Door assy. I then removed the blower motor only to find that I had indeed had a bad bearing and that my squirrel cage was the round top style. I see on your Lincoln land website that the only blower motor you sell is for a flat top squirrel cage. Do you recommend I buy a flat top squirrel cage to fit a blower motor that requires it or do you have a blower motor that is compatible with a round top. If you don’t do you know where to get one and what is the part # for it. Once again thank you very much for your reply, it helped me very much.
Sincerely,
Jett

Greetings Jett –
Thanks for the update and I am real pleased that we were able to help. Yes there were some variations for the 69-71 Marks regarding blower motors and wheels. Call our office and ask to speak to Al. Refer him to your recent blog post. We should be able to find correct parts that will work fine for you as the availability of these parts is constantly changing. Al is aware of this and he is very good at sourcing hard to find items from the aftermarket as well as our inventory. Do not throw out any of your used blower motor parts as they may be needed for rebuilding in the future.
Sincerely,
Bill
